'IM PROVEM ENT IN IC-MACHINESW.

Specification forming-part of VLetters Patent No. 198,831, dated January 1, 1878; application iiled August 6, 18,77. l

To all whom fit may concern:

Be it known that I, ALBERT ALBERTsoN, of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Processes for Making Ice; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, referencel being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to that class of improvements employed in the vmanufacture of artificial ice by the use of compressed atmospheric air, either direct from a force-pump or v from a storing-reservoir, or lfrom both, at the same time the pump being operated by any suitable motor power, either to charge the reservoir with compressed air, to be kept in reserve, to be used separately or in combination with the air-pump, to charge the double walled non-conducting ice-forming chamberD with said compressed air bymeans of suitable valves and pipes, arranged as shown in the drawing, or otherwise, to lsuit the exigencics of the situation.

The air or force pump and storing-chamber or reservoir are arranged on the outside of the icechamber D, and connect with the same by means of any suitable pipe and valve or regulating cut-off. 4(See drawing.) The iceforming core A in chamber D is provided with a short journal at each end thereof, to hold it A (the core) 'on a vertical line with the axis of the driving-roller B, operating under the wal ter in the tank C by means of any suitable outside gearing. These journals are held on a line as the revolving core A rises by the increasing jacket of ice forming around the same by means of slotted uprights secured to the sides of the tank C on aline opposite to each other.

I cover the submerged driving-rollerB with a iiexible covering, which acts upon the iceforming core A with better results, andI also employ a circular cutter upon each end of the of the core A free rfrom ice during the process of forming the same.

The storing-reservoir is charged with twenty or more atmospheres when the valve is closed, connecting it with the air-pump, and this compressed air is held ready to be thrown broadcast and utilized in the ice-chamber D when an' increased volume of air is required to more l rapidly absorb the caloric in the said freezingchamber D for the purpose of producing ice.

My Patent No. 115,409 fully covers the use of compressed air revolving hollow cores operatin g between two rigid submerged drivingrollers arranged in an ice-forming chamber without specifying from what source the air is' received or compressed. Therefore my present invention is confinedto the improved mode of supplying the freezing-chamber D with compressed air by an air-pump alone, or by the combination of the pump and storing-reser 2. The ice-core A, in combination with rotary cutters to free said core of accumulated ice, as and for the purpose set forth.

3. In an ice-forming machine, the flexible roller B provided with cutters, as described, in combination with the ice-forming core A, as and for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
